Type A botulinum toxin, commonly known as botox, is a neurotoxin produced by the bacterium Clostridium botulinum. It is widely used in aesthetic medicine to reduce expression wrinkles, but has other medical applications.

How it works:
Type A botulinum toxin temporarily inhibits the transmission of nerve signals to muscles, causing them to relax. This has the effect of reducing the appearance of wrinkles caused by muscle contraction. The treatment involves injections of botulinum toxin type A into specific areas of the muscles. The procedure is relatively short and painless, with little or no discomfort to the patient.

Duration:
The results of botulinum toxin type A usually last 4-6 months, but this may vary depending on the area and the individual.
